Hi Everybody,

In our CFD analyses, Structured hex meshes are what we mostly work with, set up using ICEM. However, when we export to CFX for setting up the boundary conditions and solving, the mesh has to converted to an Unstructured mesh.

I'd like to know : Why? and How exactly does this take place, considering the mesh doesn't look unstructured once the conversion is done!?

Please feel free to point me to literature that provide explanations.

Wikipedia and the Ansys website mention that CFX utilises a Control Volume based Finite Element discretisation scheme. I'm not very clear what that implies either.

Thanks for your help!
